Control of blood-transmitted infections in dentistry.
As knowledge has accumulated on the blood-transmitted pathogenic agents, the contact with biological fluids (blood, plasma, saliva, etc.) from apparently healthy individuals has started to be regarded as a real professional risk for dentists. Theoretically, exposure to a contaminated biological specimen may have as a consequence transmission of infection from patient to dentist, from dentist to patient and from patient to patient via inadequately decontaminated and sterilized dental equipment. The present study is concerned with the analysis of the specific conditions that favor the occurrence of the epidemic process, the estimation of the risk degree of transmission of infections caused by hepatitis B, C viruses as well as of HIV infection in Romania. The data for the study were collected using two processes. First a self reporting survey and secondly an experimental procedure were performed. The testing of dentists' knowledge of blood transmissible diseases and infection control in their offices were performed using a questionnaire with 129 questions. The professional incidents/accidents representing a potential risk were counted using a questionnaire (with 37 questions). Serological markers were tested with ELISA kits. The monitoring of sterilization was accomplished with a questionnaire and biological tests. Many conclusions result from the study. There is an extremely reduced probability and infection transmission from the dentist to the patient. The transmission of infection from the patient to the dentist represents a low risk (for all that, the risk should not be minimized). The rigorous control and observation of infection prevention measures in dental offices is necessary to stop the infection transmission from patient to patient. The dentists' postgraduate training in infection control measures should be completed with knowledge regarding the blood transmissible infections epidemiology. Learning more about the epidemiological process enables the dentists to avoid wrong attitudes and behaviors.
